I am trying to create a jar in IntelliJ through maven clean-compile-package. Build is sucessful but I am not getting class and packages in tha jar. Please help! I got below warning in logs:
[WARNING] JAR will be empty - no content was marked for inclusion!
maven project have default standard directory layout its documented here
if you not followed them or moved folders around, maybe changed output folder or similar action was taken, maven can't correctly decide how to include your class files.

We have a project which we build with gradle. We use IntelliJ as our development environment.
We have some resources we want to keep outside the JAR and so we have put them in the src/dist-folder. This works fine when running the application from the command line, but not so good when we want to debug from IntelliJ.
We could put a runtime-dependency to src/dist, but then we end up with files inside our lib-folder in the generated ZIP file and that's not what we would like to have.
Bottom line: how can we keep some resources outside the JAR (in src/dist) and also on the classpath of IntelliJ (as generated by Gradle; I don't want to have to add things manually to the IntelliJ classpath). The directory structure in the resulting zip should be something like:
root
|
|- config/*
|- css/*
|- lib/*
It seems that this question describes a similar problem, but the solution in addition #4 still mentions that no solution was found to correctly get the resources on the classpath of IntelliJ:
Gradle build file with conf folder with properties not in jar but on classpath
The solution I've used in a similar situation is to:
Use the Idea plugin in gradle rather than relying on the IntelliJ support.
Once that is working you can tweak the source path that IntelliJ uses in the gradle file itself
I'm trying to create an executable jar from IntelliJ.
First I got the Java Security Exception and I changed sqljdbc4-4.0 to unsigned. First problem solved.
Then I got Manifest not found. Added META-INF dir to output. Second problem solved.
Next I got the BeanCreationException (unsolved):
Caused by: org.springframework.beans.factory.BeanCreationException: Cannot determine embedded database driver class for database type NONE. If you want an embedded database please put a supported one on the classpath.
In IntelliJ it is working.
I think the resources are not in the output. (application.properties, ...)
In which way do I add the resources or where are they stored in the jar.
I'm using gradle and on the spring boot homepage are only instructions for maven.
You should use spring-boot-maven-plugin or spring-boot-gradle-plugin, depending on your preferred build system.
EDIT:
Just run ./gradlew build
I suggest to dive into this getting started guide. It clarifies a lot of stuff for beginners.
A typical Spring boot project is a Maven project or a Gradle-Project (I only know how to do it with Maven, for Gradle see [luboskrnacs answer][1]). So you just need to run the maven targetpackageand pick the jar form the (created)target` folder
use a shell, go to the project root directory (where the pom.xml file is) and type
mvn clean package
cd target
the there is the xxx.jar file.
I created a Maven project and imported it in Intellij IDEA.
In a run configuration, there is a field "working directory", which points to the root of Maven project.
If I change this folder, it doesn't seem to affect anything. So what is it?
This is the directory that is set as the Java user.dir system property. If you have any code that creates relative files or directories, it will be relative to this directory. So for a well designed application (i.e. resolves resources from the classpath and is configurable for output directories) this will not be a factor. There is also some importance to this value in maven projects, especially multi-module maven projects. This directory specifies the directory IDEA will read the POM from.
If you are unflamilar with what the Java user.dir is, there is some discussion available here and in the class level Javadoc for the File class.
In addition to answer given by #Javaru if you want to update or view your working directory in IntelliJ IDEA go to:
Run | Edit Configurations | Configuration Tab | Working Directory
From the IntellJ help Run/Debug Configuration: Maven
Working directory Specify the path to the Maven project file pom.xml.
We are trying to setup a number of Gradle (v1.5) web projects in IntelliJ v12.1.2
The new JetGradle integration works fine until we get the the Artifacts
The module is imported as a Gradle project, the artifact is been created as a Web Application (Exploded) and the Web facet has been added - all the dependencies that are declared in the build.gradle file are correctly added to the WEB-INF/lib directory in the artifact
The problem comes when we make a change to the dependencies in the build.gradle file and refresh the module using the JetGradle refresh button - the dependencies of the module are updated correctly but nothing is changed in the artifact
If we changing just one dependency then the change can be done manually but if there are a number of changes or there are a lot of new/changed transative dependencies then it seems the only timely way to get the correct dependencies in the artifact is to delete and recreate it
Am I missing something obvious, does anyone know a better way to update the artifacts
Thanks
Automatic artifact config update is not implemented yet. I've created corresponding ticket for that - http://youtrack.jetbrains.com/issue/IDEA-109369
I created a simple Maven project (Packaging type - Jar) that has dependencies on Spring and My Sql library (mysql-connector). When I package this project with $mvn package I do get a jar file after successful execution of this command.
I was also trying to include all the dependencies in the output jar file, so I added a 'jar-with-dependencies' assembly descriptor, but as the documentation says:
The `jar-with-dependencies` descriptor builds a JAR archive with the contents of the main project jar along with the unpacked contents of all the project’s runtime dependencies.
I want to include the dependencies in JAR form, not the unpacked way. How can I do this?
Java cannot load classes from jars in your jar out of the box. You must configure it with project like one-jar and maven plugin.
Maybe this can help Maven Shade Plugin:Maven Excecutable Jar

Vicky is trying to aggregate the jars and this is known as "building-an-aggregate-jar" in Maven's terms. You can find more in Robert's[1] and Artifact Technical Notes'[2] blog.
One discussion[3] that can help as well.
